Absolutely the worst service I have ever endured

1st delayed at a till when a customer ahead needs to buy a lightbulb but it doesn't scan (goods already unpacked from trolley). The manager then leaves with the bulb taking an inordinate amount of time before returning. In fact by the time we had reloaded our trolley and moved to another counter he had still not returned. This was easily almost 10 min. Kindly, we were escorted to another till by one of the packers who reserved the 2nd counter for us. Then another hold up when a shopper wishing to buy airtime (already at the till when we arrived) is delayed by staff unable to understand his purchase. FOUR airtime vouchers on a single card payment - what was so difficult to understand. This becomes even more bizarre when I tell you that there were FIVE different staff members involved in deciphering the purchase! After making payment I then moved to the kiosk to purchase electricity. What a disaster. PC switches off after paying and i'm unable to get prepaid electr. The same manager from about 20min earlier blurts out, \they must just wait a minute". He then walks off to take photos of the tills on a cellphone without explanation. Altogether about 25min worth of waiting in quiet PnP"""
